Multi-functional battery management system and its applications

For the research of paralleled battery characteristics,a new multi-functional battery management system(BMS) was developed,which could measure branch currents and calculate each paralleled battery’s state-of-charge(SOC),and also could measure battery voltage and temperature,and communicate with other apparatus.The hardware and software structures of the BMS were introduced and its branch-current measured ability was highlighted in this paper.The voltage calibration principle and method were presented.Also,the results obtained in the paralleled battery characteristics research were discussed.At last,a battery life test platform was introduced,which validated the reliability and durability of BMS.
